Abstract

Harbour resonance provides a possible way to amplify wave energy for wave energy converters (WEC) operating in regions with medium wave energy density. In the present paper, we conducted computationally a study on the amplification effect for a cylindrical caisson for different incidence angles of wave and wave numbers. Also studied here is the effect of some appendages on the caisson on wave amplifications. The open source code OpenFOAM was employed for all computations. The volume of fluid (VOF) method was employed to obtain the free surface. Features of wave patterns inside the caisson are also discussed. The results show that proper combinations of these parameters can result in significant wave amplifications in the caisson.
